The TDA8444 contains eight programmable 6-bit DAC outputs, an I2C-bus slave receiver with three (two for SO16) programmable address bits and one input (VMAX) to set the maximum output voltage. Each DAC can be programmed separately a 6-bit word to 64 values, but VMAX determines the maximum output voltage for all DACs. The resolution will be approximately 1/64VMAX. At power-on all DACs are set to their lowest value.

P82B96TD : Dual Bi-directional Bus Buffer.the P82B96 is a Bipolar ic That Creates a Non-latching, Bi-directional, Logic Interface Between The Normal i C Bus And a Range of Other Bus Configurations. It CAN Interface i C Bus Logic Signals to Similar Buses Having Different Voltage And Current Levels.
